Poisoning of resin supported catalyst

Abstract

A combined hydroformylation/reduction reaction is enhanced by the control of halide concentration in the feed olefin, solvent and solid supported transition metal complex catalyst to produce higher initial reaction rate and longer catalyst life.

What is claimed is: 
     
       1. A method of enhancing performance of a combined hydroformylation/reduction reaction of an olefin liquid feed in the presence of a resin-supported transition metal complex catalyst, the method comprising the steps of: (a) preparing a resin-supported transition metal complex catalyst for use in a combined hydroformylation/reduction reaction substantially free of halides and halide salts in said metal complex catalyst; and   (b) introducing an olefin liquid feed to the resin-supported catalyst for conducting a combined hydroformylation/reduction reaction, in the presence of CO and H 2 , wherein the olefin feed has a specified maximum limit of halide concentration sufficiently low to enable continued indefinite operation of the combined hydroformylation/reduction reaction process without halide poisoning.   
     
     
       2. The method of claim 1 further including the step of addition of a solvent to the feed. 
     
     
       3. The method of claim 2 wherein the solvent is maintained at specified limits of halide concentration. 
     
     
       4. The method of claim 3 wherein the halide concentration of the feed and solvent is maintained below 100 ppm. 
     
     
       5. The method of claim 1 wherein the enhanced performance is a higher initial rate of reaction and a longer catalyst life. 
     
     
       6. The method of claim 1 wherein the halide is chlorine. 
     
     
       7. The method of claim 1 wherein the metal complex catalyst contains rhodium. 
     
     
       8. The method of claim 1 wherein the olefin liquid feed is dicyclopentadiene. 
     
     
       9. The method of claim 1 wherein the catalyst support resin is a tertiary amine. 
     
     
       10. The method of claim 1 wherein the reaction is carried out at a temperature of at least 80° C. and a pressure of at least 1000 psig. 
     
     
       11. The method of claim 1 wherein the temperature is 130° C. and the pressure is 4000 psig. 
     
     
       12. The method of claim 1 including the preliminary step of removing substantially all halide ions from the catalyst by washing in a strong base. 
     
     
       13. The method of claim 1 wherein metal halides are eliminated from the preparation of the catalyst. 
     
     
       14. The method of claim 9 wherein tertiary amine in HCl form is converted to a halide free form by washing with a strong base. 
     
     
       15. The method of claim 9 wherein quaternary impurities on the tertiary amine resin in the halide form are converted to a halide-free form by washing with a strong base. 
     
     
       16. The method of claim 1 wherein the halide concentration of the feed is maintained below 100 ppm.
